So you ended up with the TR224 with a 114 LSA? Get the tuning done so we can hear it. My engine is coming apart in a week or so and we're going to see if my valve events are off. I will have a TR224 sitting next to me at the same time. If the valve events are off, I'm going to correct it and try again. If they're spot on then the TR224 is going in. I just haven't decided on a LSA yet. That's why I'm looking forward to hearing yours so hurry!

 

Both my Ho with the 6.0L and TR224 and my Silverado with the 5.3L and 222/224 Comp cam have a 112LSA.

 

Interesting, welp get us some audio clips of the idle quality

 

Tell us more about that TR224! How high do you rev that thing?

 

I've only had it about as high as 5800 at this point. I want to get it on the wideband and tuned in better before I stretch it's legs. In an LQ4/LQ9 with exhaust manifolds I'd only run it to about 6200 and with headers 6300-6400 if you were trying to get everything out of it. With a truck intake I couldn't see any gain going any higher than that. Even my 5.3L only goes to 6400-6500 for the 1-2 and 6300-6400 for the 2-3.

 

You honestly think you're making more power with those 862's than 317s?

 

Horsepower wise I doubt it. If I am gaining hp it's only from the compression difference they give me. I gained alot of compression out of the deal. I did have Fererra 2.00" intake valves installed which are a gain over even stock 2.00" 317 valves. Other than smaller ports I gained on compression and a better intake valve. My goal was to gain alot of torque. I went from a stock 5.3L to a 6.0L with 10.8:1 compression and a cam. I've driven LQ4's with just the cam and the stock 317's and they do not have the torque I have currently and mine isn't tuned in yet. If I can make the same hp at 10.8:1 compression as the stock 9.4:1 compression with the head change and pick up torque than I feel I gained something. I also plan on running E85 in it alot and that is where I also feel I will gain alot. Fuel milage on E85 is commonly considerably better with higher compression engines. After I spend some time with it I plan to dyno it and run it at the track. In spring I'd like to pull the heads and go back through and port them. I could change them to 243's, but ported 862's have made very good power on the dyno and I already have them. At this point the wife is driving it today to see if it's going to be fast enough for her.

 

Glad you got it running now Mike.

I think we all know the answer will be something like "Its ok, what are we doing to it next?"

 

Thanks, I feel better having gotten something accomplished lately. She won't be happy really unless it's faster than my truck. That's all she really wants.

As for the heads also, do some searching over at LS1Tech. There is alot of capability in them when ported and there are alot of quick 5.3L's on here with them still stock. I've seen an F-body put down over 400RWHP with them ported with only a TR220 cam.

 

I don't know why people get down on them just because of the smaller port. Actually leaves a little more room for shaping while not enlarging the port too much. That and a good valve and you are in business.
